Abstract
Recently Cherednik and Feigin [arXiv:1209.1978] obtained several RogersRamanujan type identities
via the nilpotent double affine Hecke algebras (NilDAHA). These identities further led to a series of dilogarithm identities,
some of which are known, while some are left conjectural. We confirm and explain all of them
by showing the connection with Ysystems
associated with (untwisted and twisted) quantum affine KacMoody algebras.
Key words:
double affine Hecke algebra; dilogarithm; Ysystem.
